The four major parts to the neuron are the dendrites, soma, axon hillock and terminal boutons.
The dendrites receive input from other neurons, and integrate this information into the cell. They may result in either temporal or spatial summation which may result in depolarization of the cell.
The soma, or cell body of the axon contains all of the organelles of the cell - the nucleus, mitochondria, etc. and is important for maintenance of the neuron.
The axon hillock is the area of the cell with the highest number of ion channels present in the membrane, and also is the area of the cell that demarcates the start of the axon. From here, upon summation of stimuli, an action potential can be generated by the massive influx of ions into the cell, resulting in the generation of the action potential which is propagated through the axon.
At the terminal bouton, this is where the action potential triggers a response. Using the neuromuscular junction as an example, when the action potential reaches the end of the terminal bouton, Ca2+ influx is triggered at the endplate resulting in the release of neurotransmitters, in this case, Acetylcholine, which causes contraction in the muscle.

When two neurons are separated by a synapse which two parts of the neurons meet?
In a synapse, the terminal of the presynaptic neuron and the dendrite or cell body of the postsynaptic neuron meet. The presynaptic neuron releases neurotransmitters into the synaptic cleft, where they bind to receptors on the postsynaptic neuron, allowing for communication between the two neurons.

What are the parts of neuron and its function?
The three main parts of a neuron are the soma (cell body), the axons, the long trailing output of a neuron and the dendrite or dendritic tree. Almost all neurons have axons, but not all axons have a dendritic tree.

What are the parts of a neuron and what the different parts do?
parts: cell body, dendrites, and axon. i don't know what they do though..
What are the two parts the neuron is split up into?
There are actually 3 parts to a neuron. The dendrites are tree branch like projections that receive nerve impulses from another neuron, the cell body that contains the nucleus, and the axon, a long fiber that carries the nerve impulse away from the cell body to the next neuron.
Name the 3 main parts of a neuron?
The three main parts of a neuron are the dendrites, the axon, and the soma. The dendrites are the nerve endings, the axon is the body, and the soma is the cell body.
Number of parts in a neuron?
It depends on the neuron. They all have a cell body. They have dendrites and some have dendrites plus axon(s).
